A diagram of the pulsation cycle of Type I Cepheid variable stars that I made for my astrophysics lab class.
I could probably make the wording better on the descriptions… I’ll upload an improved version after finals (I feel like I should include that step 4 happens because the helium is now too cool to counteract the star’s gravity any longer)
[13:12] <kororaa> help
[13:12] <kororaa> what’s the difference between an rr lyrae and a type ii cepheid
[13:39] <KAHR-Alpha> kororaa: doing astronomy?
[13:39] <kororaa> yes
[13:39] <kororaa> i got the answer though
[13:39] <kororaa> kind of
[13:39] <KAHR-Alpha> ah
[13:40] <kororaa> rr lyraes have a way shorter period but i can’t find a place that says why
[13:40] <kororaa> maybe they use nuva-ring
